Abstract

In this paper, the use of the supplementary controller of a Unified Power Flow Controller (UPFC) to improve damping of oscillations in Single Machine Infinite Bus (SMIB) system is investigated. The controller was designed based on a linearized modified Phillips Heffron model of SMIB in state space form. In practice systems use simple Proportional Integral (PI) controllers to control UPFC. However, since the PI control parameters are usually tuned based on classical or trial-and-error approaches, they are incapable of obtaining a good dynamic performance for a wide range of operation conditions. To address this problem, in this research an optimization approach, based on the Genetic Algorithms (GA) method is proposed for the design of UPFC controller (supplementary damping controller) for increasing damping of power system oscillations is developed. Several linear and nonlinear time-domain simulation tests clearly show the effectiveness and validity of the proposed method in enhancing of oscillations damping. Comparisons between the performances of both the proposed and conventional supplementary controllers are made. Computer test results show that proposed method is very effective in oscillations damping and in the meantime is more robust than its conventional counterpart.
